What we need is an effective FDD-Drive-SD based, that could read disk images.
I have one SD Drive Nuxx for my Atari XE, and believe me it works great. I've purchased
one 1541 ultimate for my C64 either, they're expensive yeah but worthy.
You can VIRTUALLY have EVERYTHING in a single SD... Plus you can have AN EXTRA SD
AS BACKUP, just in case the main one gets ruined or lost.

I've seen one of these projects that could be used on a different range of machines,
from Speccies to Miggies.
My problem with this device is the fact i don't know if it can be handled without screen,
SDNuxx and 1541Ultimate, display a boot-up menu to choose the desire images to use.
That's the way forward, we can use .adf's from our workbench, we can read'em
we can copy'em and use them virtually, but we can't boot from them.
One of these SD-Floppy drives would allow us to have all the bootable adf's stored
on a fistful of SD's, boot from them if we want, or manage them from Workbench.
So i don't feel in any way sad or threatened if 3,5 inch floppies vanish from earth.
In fact i only have around 40 floppies to work with them. I have all my stuff on
virtual adf's.
